In GEOPAK SS2 I could easily create a surface from a corridor and a tin file would be automatically generated. I could then extract a profile from this tin and draw it on a profile cell using the Draw Profile command. In SS3 how do I create a tin (or a terrain) from a corridor so that I can continue to show an extracted profile using SS2's Draw Profile command? An example of this is analyzing EP profiles for low points that might be caused by superelevation transitions for instance, and many other situations.
